Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.

This report describes an evaluation of an integrated ion exchange regeneration process for perchlorate treatment in drinking water. Integrated ion exchange combines: conventional ion exchange with perchlorate selective resin for wellhead treatment of perchlorate contaminated water, regeneration of resin using tetrachloroferrate (FeCl4-) anion and then returning the resin to service, and the destruction or disposal of perchlorate recovered from the resin.

This document compares the energy requirements for the removal of micropollutants in drinking water treatment plants by ozonation and O3/H2O2. The energy requirements for both treatments are in a similar range however O3/H2O2 reduces the contact time and bromated formation.

Three emerging treatment technologies, including membrane filtration, advanced oxidation processes (AOPs), and UV irradiation, hold great promise to provide alternatives for better protection of public health and the environment and thus are reviewed in this paper. The emphasis was placed on their basic principles, main applications, and new developments. Advantages and disadvantages of these technologies are compared.
